Part of the motivation of this paper comes from the recent paper [W. Guo and H.-Z. Zhou, SIAM J. Control Optim., 57 (2019), pp. 1890–1928], where an adaptive control approach was used to estimate in r...
针对无缝内衣机织针编织过程固有频率理论模型少、编织过程织针振动特性难捕获等问题,采用Euler-Bernoulli梁理论对织针沿针筒切向方向的振动方程进行求解,获取织针横向弯曲的振型曲线及固有频率,同时采用ANSYS仿真软件对第2退圈三角上6个出针位置进行模态分析。对比理论数值结果发现二者振型一致,固有频率相对误差不超过2.3%。采用德国PCO公司DIMAX系列高速相机,获取织针沿三角弧面做受迫运...
In this paper, a group shift is an expansive action of Zd on a compact metrizable zero dimensional group by continuous automorphisms. All group shifts factor topologically onto equal-entropy Bernoulli...

关于Euler-Bernoulli 梁几何非线性方程的讨论
Euler-Bernoulli 梁 几何非线性 轴向应变 弹性曲线 曲率
2013/10/10
采用Lagrange 描述,导出了轴线可伸长Euler-Bernoulli 梁在大变形状态下的轴向应变、弹性线的曲率以及平衡方程的精确表示式. 通过引入轴线伸长率函数,并将变形后轴线的弧长作为基本未知函数之一,不仅精确地计入了轴线伸长,而且还使得问题的求解区间仍然为梁的原长.进一步给出了分别以变形前后的轴线弧长及变形后轴线的纵向坐标为自变量的弹性线的曲率公式, 讨论了在不同假设条件下轴线的应变和弹...
